Javascript js window.location不工作

我在

标签中嵌入了链接列表，例如

<ul>
<li><a href='/111'>Link1</a></li>
<li><a href='/555'>Link1</a></li>
<li><a href='/444'>Link1</a></li>
<li><a href='/222'>Link1</a></li>
<li><a href='/333'>Link1</a></li>
</ul>

TIA

如何调用

窗口。作为onclick事件处理程序导航到
方法
window.navigate_to = function(event, direction) {
    var current_location, next_url, node, prev_url, url;
    if (event.preventDefault) {
      event.preventDefault();
    } else if (event.stop) {
      event.stop();
    } else {
      "";
    }
    if (direction == null) {
      direction = 1;
    }
    current_location = window.location.pathname;
    console.log(current_location);
    node = document.querySelector("a[href*='" + current_location + "']");
    if (node != null) {
      next_url = node.parentNode.nextElementSibling != null ? node.parentNode.nextElementSibling.querySelector("a[href]").getAttribute('href') : "";
      prev_url = node.parentNode.previousElementSibling != null ? node.parentNode.previousElementSibling.querySelector("a[href]").getAttribute('href') : "";
      console.log(node);
      console.log(next_url, prev_url);
      url = direction === 1 ? next_url : prev_url;
      console.log(window);
      console.log(url);
      window.location = window.location.host + url;
      return true;
    }
};
